Abstract
Methods and products for protecting tissue of a patient during a surgical procedure that involve making an incision in the tissue and retracting the tissue to make a larger opening, wherein the methods and products use a water-absorbing stress-distributing layer.
Claims19
A method of protecting tissue of a patient during a surgical procedure, the method comprising:
- providing a water-absorbing stress-distributing layer comprising a hydrogel, a hydrocolloid, or a combination thereof;
- wherein the stress-distributing layer has opposite first and second major surfaces and at least a portion of the stress-distributing layer is greater than 2 mm thick between the first and second major surfaces;
- adhering the stress-distributing layer to the patient such that it conforms to the shape of the tissue of the patient;
- making an incision through the stress-distributing layer into the tissue;
- and
- retracting the tissue along the incision using a retractor;
- wherein the stress-distributing layer undergoes stretching and/or compression during retraction.
A method of protecting tissue of a patient during a surgical procedure, the method comprising:
- providing a flexible polymeric film having opposite first and second major surfaces;
- providing a water-absorbing stress-distributing layer comprising a hydrogel, a hydrocolloid, or a combination thereof;
- wherein the stress-distributing layer has opposite first and second major surfaces and at least a portion of the stress-distributing layer is at least 1 mm thick between the first and second major surfaces;
- placing the flexible polymeric film and the stress-distributing layer in contact with one another so that the flexible polymeric film and the stress-distributing layer are attached together to form a stress-distributing composite, and the stress-distributing composite is adhered to the patient such that the stress-distributing composite conforms to the shape of the tissue of the patient;
- making an incision through the stress-distributing composite into the tissue;
- and
- retracting the tissue along the incision using a retractor;
- wherein the stress-distributing composite undergoes stretching and/or compression during retraction.
A method of protecting tissue of a patient during a surgical procedure, the method comprising:
- providing a surgical incise drape comprising a flexible polymeric film having opposite first and second major surfaces and a pressure sensitive adhesive on at least a portion of at least one major surface thereof;
- providing a free-standing water-absorbing stress-distributing layer comprising a hydrogel, a hydrocolloid, or a combination thereof;
- wherein the stress-distributing layer has opposite first and second major surfaces;
- adhering the surgical incise drape to the patient;
- adhering the free-standing stress-distributing layer to the surgical incise drape;
- making an incision through the incise drape and the stress-distributing layer into the tissue;
- and
- retracting the tissue along the incision using a retractor;
- wherein the surgical incise drape and stress-distributing layer undergo stretching and/or compression during retraction.
The method of any one of the preceding claims wherein the water-absorbing stress-distributing layer comprises a hydrocolloid.
The method of any one of the preceding claims wherein the water-absorbing stress-distributing layer is porous.
The method of any one of the preceding claims wherein the tissue of the patient is initially treated with a presurgical skin preparation.
The method of any one of the preceding claims wherein the tissue of the patient is initially treated with a barrier film.
A method of protecting tissue of a patient during a surgical procedure, the method comprising:
- providing a presurgical skin preparation;
- providing a free-standing water-absorbing stress-distributing layer comprising a hydrogel, a hydrocolloid, or a combination thereof, wherein the stress-distributing layer has opposite first and second major surfaces;
- treating the patient's skin with a presurgical skin preparation;
- adhering the free-standing water-absorbing stress-distributing layer to the patient over the area treated with the presurgical skin preparation;
- making an incision through the presurgical skin preparation and the stress-distributing layer into the tissue;
- and
- retracting the tissue along the incision using a retractor;
- wherein the presurgical skin preparation and stress-distributing layer undergo stretching and/or compression during retraction.
The method of any one of the preceding claims wherein the retracting does not displace the stress-distributing layer from the patient along the incision while undergoing stretching and/or compression during retraction.
The method of any one of the preceding claims wherein the surgical procedure is a minimally invasive surgical procedure.
The method of any one of the preceding claims wherein the surgical procedure is an open surgical procedure.
A kit for use during a surgical procedure to protect tissue of a patient, the kit comprising:
- a surgical incise drape comprising a flexible polymeric film having opposite first and second major surfaces, a pressure sensitive adhesive disposed on at least a portion of at least one major surface of the film, and a release liner disposed on the pressure sensitive adhesive;
- a water-absorbing stress-distributing layer having opposite first and second major surfaces, and a release liner disposed on at least one of the surfaces;
- wherein the water-absorbing stress-distributing layer comprises a hydrogel, a hydrocolloid, or a combination thereof;
- and
- sterile packaging enclosing the surgical incise drape and stress-distributing layer.
A kit for use during a surgical procedure to protect tissue of a patient, the kit comprising:
- a water-absorbing stress-distributing layer having opposite first and second major surfaces, and a release liner disposed on at least one of the surfaces;
- wherein the water-absorbing stress-distributing layer comprises a hydrogel, a hydrocolloid, or a combination thereof;
- a presurgical skin preparation;
- and
- sterile packaging enclosing the stress-distributing layer and the presurgical skin preparation.
A kit for use during a surgical procedure to protect tissue of a patient, the kit comprising:
- a flexible polymeric film having opposite first and second major surfaces, a pressure sensitive adhesive disposed on at least a portion of at least one major surface of the film, and a release liner disposed on the pressure sensitive adhesive;
- a water-absorbing stress-distributing layer having opposite first and second major surfaces, and a release liner disposed on at least one of the surfaces;
- wherein the water-absorbing stress-distributing layer comprises a hydrogel, a hydrocolloid, or a combination thereof;
- a presurgical skin preparation;
- and
- sterile packaging enclosing the surgical incise drape and stress-distributing layer.
A stress-distributing composite adhered to the skin of a patient, the stress-distributing composite comprising:
- a presurgical skin preparation on the skin of the patient;
- and
- a water-absorbing stress-distributing layer having opposite first and second major surfaces;
- wherein the water-absorbing stress-distributing layer comprises a hydrogel, a hydrocolloid, or a combination thereof;
- wherein at least a portion of the stress-distributing layer is at least 1 mm thick between the first and second major surfaces;
- wherein the water-absorbing stress-distributing layer is adhered to the presurgical skin preparation on the patient's skin.
A stress-distributing composite adhered to the skin of a patient, the stress-absorbing composite comprising:
